As for querying and errors, without going into prepared statements, you can almost use what you have. The mysql_query is replaced with mysqli_query, and the parameters are reversed. So the $link is ALWAYS required and is the first argument.
The error calls are the same, just again with mysqli_error/errno instead of the mysql_error/errno.
So your previous use of $link as a requirement, will actually help you with the conversion process.

Hi Fou-Lu ...
Many thanks for your advise.

I didn't realise how easy it was.
I have tried in the past, but I think that I didn't put $link first, so it didn't work.
I made the same mistake this time, but went back to your post a read it more closely.

I have now changed my current project to mysqli.
I will now change all my other database projects.
